Babbar Sanda Mai Tsabtace Tagulla Mai Kyau - Shirye-shiryen Injin Daidaitawa

Fassarar Turanci ta Ƙwararru: Hanyar Tsarin Samarwa (Cikakken Sarrafa Cikakke Mai Aiki da Kai)

1. Zaɓin Kayan Danye Mai Kyau na Tagulla Mai Kauri na 1 (Cu-CATH-2) wanda aka samo daga manyan masana'antun jan ƙarfe na lantarki a Guizhou, Jiangxi, da sauran yankuna, tare da cikakken sarrafa ƙazanta a ≤ 35 ppm.

2. Tsarin Narkewa Narkewar tanda biyu ta amfani da tanda mai ƙarfin lantarki + matsakaicin mita, wanda aka kare shi ta hanyar wani abu mai rufewa na gawayi + graphite mai tsabta, kuma an kare shi da yanayin nitrogen/argon gaba ɗaya don rage ɗaukar iskar oxygen. Ana sarrafa yawan iskar oxygen a hankali a 5-15 ppm.

3. Jefawa Mai Ci Gaban Juyawa Sama Mai Ci Gaba (hanyar zana sama) tare da crystallizer mai ƙarfi na graphite. Sigogi na jan hankali da aka sarrafa daidai (gudun zane, lokacin dakatarwa, da lokacin turawa baya an daidaita su sosai). Nauyin ingot: tan 1.5-2.5, yana tabbatar da ingantaccen tsarin hatsi na ciki kuma babu wani rarrabuwa mai mahimmanci.

4. Tsarin Dumama Tanderu mai amfani da iskar gas mai sassa uku, mai dumama iri ɗaya a 800–850 °C, lokacin riƙewa ≥ awanni 4, yana kawar da porosity da rarrabuwar abubuwa ta hanyar da ta dace.

5. Mashin ɗin hydraulic mai zafi mai nauyin tan 3200–5000, rabon extrusion 30–80, zafin ganga na extrusion 750–800 °C, saurin fita 30–80 mm/s, wanda ke haifar da saman da babu rubutu mai launin lemu da kuma tsarin ciki mai yawa.

6. Zane / Matakalar Na'ura Mai Na'ura Zane mai sanyi mai wucewa da yawa tare da matsewa mai matsakaicin mita (580–620 °C a ƙarƙashin yanayin kariya). Juriyar girma mai yiwuwa zuwa ±0.10 mm, ko ±0.05 mm don buƙatu na musamman.

7. Kammalawa Mai miƙewa shida-birgima + niƙa mara tsakiya, cimma ƙazanta a saman Ra ≤ 0.8 μm (Ra 0.4 μm yana samuwa idan abokin ciniki ya buƙaci).

Manyan Ma'aunin Inganci (Matsakaicin Rukunin 2024–2025)

● Juyawar karkace (gwajin juyawa na mita 1): ≤ 5 mm
● Juriyar Girma: Daidaitaccen ±0.15 mm; daidaitattun ma'auni ±0.08 mm
● Lalacewar saman: Ba shi da tsagewa, naɗewa, haɗe-haɗe, da kuma yanayin bawon lemu
● Gwajin halin yanzu na Eddy: Ya dace da GB/T 5126 Aji na B
